Geektastic: I would only ever vote to keep a left wing candidate from being elected
You are part of the reason why giving a government power doesn't mean endorsement of their policies.
The Australian public just did this en masse. "We don't like Labor so we'll vote for the other guy. We actually don't like his policies at all. BUT WE CAN'T HAVE LABOR BECAUSE.....LABOR"
Now many of them are going "oops" (based on today's poll - huge swing giving Labor majority with preferences)
